Is there only By on the base B? If so, is the B vector still calculateable with trigonometry, or the only force there will be By, without any Bx?

Homework Statement Given: AD=DC = 9m P=78kN S=25Kn Angle alpha = 35 deg A is static but B is movable I need to solve forces on the bases A and B I do not understand where do I mark the forces if there is a base that can move. Homework EquationsThe Attempt at a Solution My attempt: I am...

So this is correct as well? I guess I found my mistake.

Oh sorry.. the image was not uploaded. Here:

Why am I getting a negative Cy, when it should be positive?

Im sorry. Could you please tell me where I am wrong again? I am using the same methodology, but I have a feeling its incorrect, cause I can't find the second force momentum equation. The A, Ax, Ay, C , Cy and Cx is added by me. Everything else was given.

Great! Thanks! To both of you. So my mistake was that I tried to make components of F and G from P? While I actually had to make them from the F and G itself.

Is this correct?

I hope I understood correctly what you asked due to the language barier. But I guess this is what you meant:

Like this?

In the picture F and G is Fw and Fv. Is that right? In that case components are. P/sin45 and P/sin20 for the y axis. And P*cos45 and P*cos20 for the x axis. Atleast if I got it right.

I also don't get why on the second equation both magnitudes have to be equal? Id say they won't be equal, since the angles are different

I am a bit confused. Is this equation for the projection of all forces on y-axis wrong?

Well the R should be right above the P in that case, which cancels the P itself. But that didnt help me out. Or I am drawing something incorectly
